Yesterday, suddenly, movies that had been playing flawlessly started having problems. The only piece of software that was installed prior to my noticing the problem was MeGUI.

I have "WALL-e" encoded as an .mp4 with AAC and h264 at 1280x720. It's a 1.5 GB file. Two days ago after I finished its conversion. I tested it and it work flawlessly. I have "A Clockwork Orange" encoded as an .avi with AC3 and Xvid MPEG2. It's a 1.8 GB file. Tested after conversion--flawless.

Yesterday evening. I notice stuttering in a movie that I downloaded. I get curious and test the above files to see if its a problem with the encoding on the file I downloaded. Wall-e is now completely unwatchable, and ACO pauses every second or two.

I've tested other files like episodes of Rome and The Office, they seem to be working fine.
